The 2010 Infiniti M35 sits in the later years of Infiniti’s rear-drive sport-luxury sedan formula, blending executive comfort with a more athletic chassis than many midsize luxury cars of its time. That balance matters when it comes to tires, because this exact model uses two different radial fitments depending on sub-model: 245/45R18 or 245/40R19. The choice is less about vintage construction and more about confirming whether the car is a Luxury, Sport, or X before comparing tire options. From there, the decision centers on the correct rim diameter, series selection, and a blackwall tire that suits the car’s road manners and overall presentation.
Which Tire Size Is Right for The 2010 Infiniti M35
The 2010 Infiniti M35 uses two primary tire sizes, and the correct one depends on the exact sub-model. Luxury and X models use 245/45R18, while the Sport uses 245/40R19, so the first step is confirming both the trim and the wheel diameter already on the car. Once that is settled, the decision moves to comparing radial tire series, brand options, and wheel-width compatibility within the proper size.
A 245/45R18 size identifies a metric radial tire with a 245-millimeter nominal section width, a 45-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2010 Infiniti M35, this is the radial fitment used on the Luxury and X sub-models, making it the right starting point for those cars. Available choices include BFGoodrich and Nitto products in blackwall form, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is the one to evaluate when the car retains its 18-inch wheel setup and the goal is matching the proper fitment before comparing performance-oriented tire character.
A 245/40R19 size uses the same 245-millimeter nominal width but a lower 40-series profile and a 19-inch rim diameter, all in radial construction. On the 2010 Infiniti M35, this size belongs to the Sport sub-model and should not be treated as the universal fitment for every M35 configuration. Product choices in this size include blackwall BFGoodrich options from the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. This is the size to focus on when the car carries the factory-style 19-inch wheel diameter or when a Sport model’s stance and wheel package need to stay aligned with its intended setup.
Sub-model fitment matters on the 2010 Infiniti M35 because the tire size changes with the trim. Luxury and X models share one size, while the Sport uses a different size and rim diameter, so confirming the exact sub-model helps avoid choosing the wrong wheel-and-tire combination.

2010 Infiniti M35 Luxury
The 2010 Infiniti M35 Luxury uses the 245/45R18 radial tire size. Tire selection for this sub-model centers on staying with the 18-inch setup and then comparing blackwall options, tire series, and wheel-width compatibility within that fitment.
The 2010 Infiniti M35 Sport uses the 245/40R19 radial tire size. That makes wheel diameter especially important, since product comparison should begin only after confirming the car is still on the proper 19-inch setup for this sub-model.
The 2010 Infiniti M35 X uses the 245/45R18 radial tire size, the same fitment used by the Luxury model. For tire selection, that means the focus stays on the 18-inch wheel package and the available blackwall radial choices offered in that size.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2010 Infiniti M35 Tires for Sale
Available 2010 Infiniti M35 tires focus on the two correct radial sizes and include BFGoodrich and Nitto choices. Across the product grid, the main points to compare are tire series, blackwall construction, and the rim-width ranges tied to the 18-inch and 19-inch fitments.
Common 2010 Infiniti M35 tire questions usually come down to identifying the right size for the exact sub-model, confirming 18-inch versus 19-inch wheel fitment, and comparing the available radial tire series, brands, and maintenance considerations before road use.
Tire Size & Fitment
What tire size fits a 2010 Infiniti M35?
The 2010 Infiniti M35 uses two tire sizes depending on sub-model. The Luxury and X models use 245/45R18 radial tires, while the Sport model uses 245/40R19 radial tires.
That means the correct fitment starts with identifying the exact trim and confirming the wheel diameter already on the car. An M35 that has been fitted with aftermarket wheels should be checked carefully, because choosing between the 18-inch and 19-inch sizes is not just a matter of preference.
What size rim does a 2010 Infiniti M35 use?
A 2010 Infiniti M35 uses either an 18-inch or 19-inch rim, depending on sub-model. The 245/45R18 fitment uses an 18-inch rim, and the 245/40R19 fitment uses a 19-inch rim.
Wheel diameter should be verified before selecting tires, especially on a used M35 where wheels may have been changed over time. Tire size must match the actual rim diameter on the vehicle, and wheel width should also be compared against the tire’s approved range before mounting.
Do all 2010 Infiniti M35 sub-models use the same tire size?
No. The 2010 Infiniti M35 Luxury and M35 X share the 245/45R18 radial size, while the 2010 Infiniti M35 Sport uses 245/40R19.
That difference is important because the Sport does not just use a different profile; it also uses a different rim diameter. A buyer comparing tires should confirm the trim first, then verify that the car still has the correct wheel setup before narrowing the choice to brand, series, or other product details.
Choosing the Right Tire
What should I consider when choosing a 245/45R18 tire for a 2010 Infiniti M35?
For a 2010 Infiniti M35 using 245/45R18, the main points are staying with the correct size, confirming 18-inch wheel compatibility, and comparing the available radial tire series. In this fitment, choices include BFGoodrich and Nitto blackwall tires across several performance-oriented lines.
Selection becomes more focused once the sub-model and wheel package are confirmed. Comparing rim-width range, load figures where stated, and the intended use of the car helps narrow the choice, especially if the M35 is driven regularly rather than kept as a lightly used secondary vehicle.
What brands offer tires for the 2010 Infiniti M35?
Tires for the 2010 Infiniti M35 are available from BFGoodrich and Nitto in the applicable sizes. BFGoodrich appears in both 245/45R18 and 245/40R19, while Nitto is available in the 245/45R18 fitment.
Brand alone should not be the only factor in the decision. It helps to compare which series are offered in the exact size needed, then review wheel-width compatibility, load information where shown, and how the tire’s overall character fits the way the M35 will actually be used.
What tire series are available for the 2010 Infiniti M35?
The 2010 Infiniti M35 is offered with several tire series depending on size, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. Not every series appears in both M35 fitments.
That makes the exact tire size the first filter, followed by product character within that size. A buyer choosing for a Luxury or X model has a broader mix of series to compare in 245/45R18, while a Sport owner should focus on the 245/40R19 options that match the 19-inch setup.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Infiniti M35?
A period-style 2010 Infiniti M35 tire choice starts with using the correct original fitment pattern for the sub-model: 245/45R18 for Luxury and X, or 245/40R19 for Sport. All of the available options shown here are blackwall radials, which suit the car’s modern sport-luxury presentation.
Appearance on a car from this era is usually influenced more by wheel diameter, sidewall profile, and an appropriately contemporary tire look than by vintage-style construction details. Keeping the correct size and wheel relationship intact generally matters more than chasing a dramatic visual change that alters the M35’s proportions.
Does correct tire fitment matter for a 2010 Infiniti M35 restoration?
Yes. Correct tire fitment helps preserve the intended stance, wheel-to-body proportion, and overall presentation of a 2010 Infiniti M35. On this model, that also means preserving the distinction between the 18-inch Luxury and X setup and the 19-inch Sport setup.
A restoration-minded owner should verify the actual wheels on the car before purchasing tires, since later wheel swaps can blur what belongs on a specific sub-model. Once the size is confirmed, a blackwall radial in the proper fitment keeps the look in line with the car’s original era and design language.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Infiniti M35?
Yes. Modifications such as aftermarket wheels, altered offsets, suspension changes, or lowering can affect tire fitment on a 2010 Infiniti M35 even when the tire size looks close to stock. That is especially important here because the M35 already uses two different wheel diameters across its sub-models.
A modified car should be checked for actual wheel diameter and width, plus clearance at the fenders and suspension through steering travel and compression. Verifying those details before choosing tires helps prevent selecting a size that matches the trim on paper but not the vehicle’s current setup.
What should I inspect before driving a 2010 Infiniti M35 on new tires?
Before driving a 2010 Infiniti M35 on new tires, inspect the wheels for damage, confirm the tire size matches the car’s sub-model and rim diameter, and make sure the tires are mounted and inflated properly. It also helps to check the suspension and alignment condition.
A fresh set of tires can only perform as intended if the surrounding hardware is in good order. Uneven wear, vibration, wandering, or rubbing after installation should be addressed early, since those symptoms often point to wheel, alignment, or clearance issues rather than the tire alone.
How often should tires on a 2010 Infiniti M35 be inspected?
Tires on a 2010 Infiniti M35 should be inspected regularly, not just when tread looks low. Routine checks should include air pressure, tread wear pattern, sidewall condition, cuts, bulges, and any signs of slow air loss.
Cars that are driven less frequently can still develop tire problems from age, storage conditions, or long periods of sitting. Looking over the tires before longer trips and during normal maintenance visits helps catch issues early, especially on a performance-oriented sedan where tire condition strongly affects ride quality and road manners.
